Getting in to the actual simulation part

03.15.2015

Continuation of the MES tutorial, but by now I have an idea of what matlab can do, and how I want to represent my simulation. I want to model the map that pedestrians will traverse as a grid. The things on the map like buildings obstacles and shops etc. will be represented as numbers in the grid. And the walkable area will also be represented as numbers in the grid. I am thinking to make all non-walkable cell/tile/node a positive number. That way I can represent more things and still keep the node walkable.
Pedestrians will have characteristics based on who they are. Some basic types of characters suggested by my adviser is tourist, office worker, school kid, teenager, and elderly. The model can also include time of day which will dictate what types of people are out and about. For example during school hours on a week day its we are unlikely to find kids and teenagers on the road, and more likely to find tourists. Also at the beginning of the working day and at the close of a working day, we are more likely to find office workers out and about.
So the 1st step is to get a 2d grid as a map and have a pedestrian/number navigate through obstacles. We need to make it in such a way that the pedestrian’s behaviour/ decision making can be sassily inserted into the code. For the navigation I will use the A-star algorithm as suggested by my adviser. In addition I need to show what I have visually through matlab. Ideally have it animate the data of navigation. So in the next week I will be looking at details on the a-star and how to code it.
I have to write a proposal for this too.
